Caucus day in Iowa

Omaha, NE – The Pottawattamie County Republican Party is preparing for more than double the turnout at Tuesday's caucus than in 2008.

The caucus begins at 7pm. It's the first vote in the nation for GOP presidential candidates. Naomi Leinen, co-chairman of the Pottawattamie County Republican Party, says they won't be endorsing a candidate.

She urges caucus-goers to show up to their precinct sites early. "If they're registering, either switching parties or registering as a new voter, show up maybe a few minutes early so they can get that form filled out. If they have a driver's license with their current address on it that helps speed it up, you can have someone vouch for you, but they can only vouch for someone once."

Leinen expects the caucus process to last about an hour. In addition to choosing a presidential candidate, delegates and party leaders are also chosen.
